You can all you need is a couple of cheap cactus triggers from ebay. They cost about as much as a sync cable and will open you to a world of new opportunities.

Switch's facial expression in his avatar says it all really.

The other option is to setup a small reflector. Aluminium foil and cardboard work very well on a tight budget. Set it off to the side of the camera and fire your flash into it with the zoom set as narrow as it will go. The flash is still on camera but the light will be diffused and come at the model from an angle.
